How to count the days between two dates

  1. Pick the start date and the end date. End date starts as today.
  2. Tick Include the end day if both days count, as with a holiday from Monday to Friday.
  3. Read the total in days, with the same span in weeks, months, weekdays and hours.

Common uses

  • Counting down to a holiday, wedding, exam or due date.
  • Working out notice periods, contract lengths and how long a subscription has run.
  • Checking how many working days a project or a delivery window has.
  • Finding out how long ago something happened.

Months are not all the same length

Results in months are counted the way people count them: from 15 January to 15 March is 2 months, even though the two months have different numbers of days. When a start day doesn’t exist in a later month, as with 31 January, the month ends on the last day available instead, so one month after 31 January is 28 or 29 February.
